Roland Promars Compuphonic MRS-2
Old School Electro Roland Promars Demo: Multitrack recording synthesizer demo with the Promars + TR 808 + Electrix Warp Factory Vocoder
Spiced with some FX. The Promars ( Full name is Promars Compuphonic MRS-2 ) is basically the monophonic version of the Jupiter 4, but with 2 VCO's instead of one Osc + sub. But you can't fully control the second OSC , only the detuning.
